We have reported the green synthesis of silver nanoparticles (AgNPs) using the aqueous extract of Sapodilla ( Manilkara zapota ) fruit as nontoxic and eco-friendly reducing material. The synthesized AgNPs were characterized and used for preparing nanocomposites with GO and PEDOT:PSS. We have compared the performance o…
We show how lattice quantum Monte Carlo can be applied to the electronic properties of carbon nanotubes in the presence of strong electron-electron correlations. We employ the path-integral formalism and use methods developed within the lattice QCD community for our numerical work. Our lattice Hamiltonian is closely r…
<div class="section abstract"><div class="htmlview paragraph">Lean gasoline engines offer greater fuel economy than the common stoichiometric gasoline engine, but the current three way catalyst (TWC) on stoichiometric engines is unable to control nitrogen oxide (NO<sub>X</sub>) emissions in oxi…
Mn‐doped (Bi 0.5 Na 0.5 ) 0.94 Ba 0.06 TiO 3 (Mn BNBT ) thin films were prepared on SrRuO 3 ( SRO )‐coated (001) SrTiO 3 ( STO ) single crystal substrates by pulsed laser deposition under different processing conditions. Structural characterization (i.e., XRD and TEM ) confirms the epitaxial growth of STO / SRO /Mn BN…
Palladium(0) nanoparticles continue to be important in the field of catalysis. However, and despite the many prior reports of Pd(0)n nanoparticles, missing is a study that reports the kinetically controlled formation of Pd(0)n nanoparticles with the simple stabilizer [Bu4N]2HPO4 in an established, balanced formation r…
Electrical and thermoelectric (TE) properties for n-type Ag8SnSe6 and (Ag1−xNbx)8SnSe6 are investigated. Ag8SnSe6 has the thermoelectric figure of merit (ZT) close to 1.1 at 803 K due to its intrinsic ultralow thermal conductivity ∼0.3 Wm−1K−1, relatively low resistivity ∼0.01 Ω cm, and high Seebeck coefficient ∼−200…
The antitumor effect of chemotherapeutics loaded micelles mainly depends on two aspects: the accumulation in the tumor region and the penetration into the tumor interior. These two processes have different demands on particle size. The optimal particle size for enhanced permeability and retention (EPR) is commonly bel…
Abstract Highly conductive and transparent NiO x films can be very useful as buffer layers for the optimization of the p-type contacts of optoelectronic devices. Thin NiO x films were fabricated by reactive radio frequency (RF) sputtering at room temperature starting from a Ni target. A systematic study of the influen…
The present study focuses on the use of cellulose nanocrystals (CNC) as the main constituent of a nanocomposite material and takes advantage of hydroxyl groups, characteristic of the CNC chemical structure, to thermally cross-link an epoxy resin. An original and simple approach is proposed, based on the collective sti…
Although zinc oxide (ZnO) is a widely studied nanomaterial and a useful photocatalyst, the structures predicted by traditional morphology models, such as the Wulff construction, are largely inconsistent with experimental observations. As well as being scientifically perplexing, this disparity hinders our ability to pr…
In this work we report a porous silver thin film cathode that was fabricated by a simple inkjet printing process for low-temperature solid oxide fuel cell applications. The electrochemical performance of the inkjet-printed silver cathode was studied at 300-450 °C and was compared with that of silver cathodes that were…
In this work, ZnS quantum dots (QDs) capped with mercaptopropanoic acid were applied to the hydrogen peroxide-hydrogen sulfite chemiluminescence (CL) system. The CL intensity of the system was significantly enhanced by ZnS QDs in an acidic medium. The reactive oxygen species like superoxide ion ( • O 2 – ), sulfite (…
ABSTRACT This review is focused on the use of ionomers in shape memory polymers. Ionomers are polymers that contain less than ∼15% ionic groups. The incompatibility between the ion‐pairs and the polymer backbone drives microphase separation producing dispersed ionic aggregates, which can physically crosslink the polym…
Two-dimensional high-index-contrast dielectric gratings exhibit unconventional transmission and reflection due to their morphologies. For light-emitting devices, these characteristics help guided modes defeat total internal reflections, thereby enhancing the outcoupling efficiency into an ambient medium. However, the…
Supported subnanometer clusters exhibit superiority in catalytic performance compared to common nanoparticles, due to their higher fraction of exposed surfaces and larger number of active species at the metal–support interface, responding to the size effect and the support effect in heterogeneous catalysis. Here, we r…
Various polymeric nanoparticles (NPs) with optimal size, tumor-targeting functionalization, or microenvironment sensitive characteristics have been designed to solve several limitations of conventional chemotherapy. Nano-sized polymeric drug carrier systems have remarkably great advantages in drug delivery and cancer…
Transition metal dichalcogenides (TMDs) are a class of two-dimensional (2D) materials that have attracted growing interest because of their unique electronic and optical properties. Under ambient conditions, most TMDs generally exhibit 2H or 1T structures. Unlike other group VIb TMDs, bulk crystals and powders of WTe…
ABSTRACT Poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) has been studied for a wide range of applications due to its potential as a transparent electrode. Herein, the use of imidazole and its derivatives as a neutralizing additive for PEDOT:PSS dispersion and in‐depth studies of their effects in t…
The $\ensuremath{\beta}\text{\ensuremath{-}}\mathrm{B}{\mathrm{i}}_{2}\mathrm{Pd}$ compound has been proposed as another example of a multigap superconductor [Imai et al., J. Phys. Soc. Jpn. 81, 113708 (2012)]. Here, we report on measurements of several important physical quantities capable of showing a presence of mu…
Multiferroics are promising for sensor and memory applications, but despite all efforts invested in their research no single-phase material displaying both ferroelectricity and large magnetization at room-temperature has hitherto been reported. This situation has substantially been improved in the novel relaxor ferroe…
